SPRINGBLOCK SET FOR SAWS.

Specification of Letters Patent.

Patented Mar. 3,1914.

To all whom it may concern Be it known that I, Ensnnn GODIN, a sub jcctof the King of England, residin at I-Iarrisville, in the State of New York, United States of America, have invented certain new and usefulImprovements in Spring-Block Sets for Saws, of which the following isthe specification.

This invention relates to improvements in spring block sets for saws andthe objects of the invention are to provide a portable device which maybe readily used to accurately set saws and in which the degree ofsetting may be adjusted by simple means.

Further objects are to construct the device of few and workable partsnot likely to come out of order and which may be readily used byunskilled workmen and it consists essentially of the improvedconstruction hereinafter described in detail in the accompanyingspecification and drawings.

I11 the drawings, Figure 1 is a perspective view of the device. Fig. 2is a longitudinal section of the same in position. Fig. 3 is an endelevation. Fig. 1 is a transverse section through the clamping bolt.

In the drawings like characters of reference indicate correspondingparts in all the figures.

Referring to the drawings, A represents the anvil member on which theteeth of the saw are adapted to be shaped, to which end it is formedwith an inclined portion 10 on which the teeth are adapted to be bent tothe proper inclination.

B represents a longitudinally adjustable gage member in the form of aplate, fitting within a dovetail slot 11 on the anvil member and adaptedto be held in adjusted position by suitable clamping means. The clampingmeans which I have devised comprise a threaded pin 12 in the side of thegage member extending through a slot 13 in the wall of the dovetailgroove, said pin having a clamping thumb nut 14 thereon adapted to forcea plate 15 against the side of the anvil member. For further securitythe side of the anvil member may be formed with teeth 16 adapted toreceive a single tooth 17 on the plate 15.

C represents a hammer member reciprocable to and from the surface of theanvil member, and supported by a plate spring 18 which is secured at 19to the gage member. The spring is adapted normally to maintain thehammer member in slightly raised position. The upward movement of thehammer member is adapted to be limited by suitable means, such asdownwardly projecting plates 20, secured to the sides of the springmember and having enlarged ends 21. adapted to fit within dovetail slots22 in the sides of the gage member B. The underside of the hammer memberis shaped to conform with the inclined surface 10 so that it will shapethe teeth of the saw thereto. It will be observed that the dovetail slot11 is formed by flanges 2 1 and 25 which project upwardly from thesurface of the anvil member.

For convenience in attaching the anvil member to the top of a stump orother form of support on which it is placed, it may be provided on theunder-side with a plurality of spikes 23.

The device may be used to set ordinary cross-cut saws as well ascircular saws. In using the device the anvil member is secured to asuitable support and the saw placed across the same in a substantiallyhorizontal position, each particular tooth being brought beneath thehammer member and the hammer member is then driven down on the tooth bymeans of a suitable sledge or mallet. The inclination may be regulatedby adjusting the supporting member longitudinally by the meanspreviously described.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention, within thescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in the accomipanying specification and drawings shall be interpreted as illustrativeand not in a limiting sense.

WVhat I claim as my invention is 1. A saw setting device comprising incombination an anvil member having a slot therein, a gage member mountedin the slot, means for clamping the gage member in adjusted position insaid slot, a hammer member formed with a laterally extending tongueadapted to act as a spring, said tongue supporting the hammer member andbeing secured to the gage member and means for limiting the upwardmovement of the hammer member.

2. A saw-setting device comprising in combination an anvil member havinga longitudinally extending slot in the normal upper surface thereof, agage member slidsaid means extending laterally through a slot formed inone of the side Walls of the first mentioned slots, a hammer membersupported by a plate spring formed integral therewith, said spring beingsecured to said plates on the side of the spring having engage member.

3. An improved saw setting device comprising an anvil member having adovetail slot formed on the surface by two flanges, one of the flangeshaving a slot therethrough, a gage plate mounted in the dovetail slot,clamping'means on the gage plate extending through the slot in theflange on the anvil member and adapted to bear against the side of theanvil member, a hammer member, and means for supporting the hammermember from the gage plate with freedom to reciprocate to and from theanvil member.

l. An improved saw setting device comprising an anvil member, anadjustable gage plate thereon having dovetail slots in the sidesthereof, a hammer member, a fiat spring supporting the hammer member andlarged ends fitting the dovetail slots in the gage member.

In, Witness whereof I have hereunto se my hand in thepresence of tWOWIlSI'lGSSGS.
